Abstract
Maintenance of an open sternotomy (OS) after a complicated cardiac operation is an adjunct in the treatment of the severely impaired heart. We hypothesized that predictors of the timing, morbidity, and prognosis of delayed sternal closure (DSC) could be determined by intensive case review. Prolonged OS was used in 107 of 6,030 adult open heart patients (1.8%) between 1987 and 1991. Indications for OS were hemodynamic instability (40), myocardial edema (18), intractable bleeding (23), relentless arrhythmias (9), and ventricular assist devices (17). Delayed sternal closure was carried out in 75 of 107 patients at a mean of 3.4 ± 0.3 days after OS. Fifty of these 75 (67%) survived and were discharged an average of 43 ± 6 days after closure. Fifty-seven patients died: 32 before DSC at 3.7 ± 0.8 days after OS and 25 after DSC at 27 ± 4 days after OS. Baseline cardiac index (1.7 ± 0.1 L · min
−1 · m
−2) improved an average of 1.0 ± 0.1 L · min
−1 · m
−2 after OS (
p ≤ 0.001) and remained stable through DSC (2.5 ± 0.3 L · min
−1 · m
−2) and late (9 ± 0.7 days) follow-up (2.8 ± 0.1 L · min
−1 · m
−2). Delayed sternal closure in patients without ventricular assist devices was significantly more likely to be successful (

p < 0.01 for both). This study shows that OS and DSC can now be performed with a more complete understanding of the benefits, timing, and risks of these potentially lifesaving maneuvers.
